+It controls its own number of false detections: On average, one false alarms is allowed per image. \
+The method is based on Burns, Hanson, and Riseman's method, \
+and uses an a-contrario validation approach according to Desolneux, Moisan, and Morel's theory. \
+The version described here includes some further improvement over the one described in the original article.");
